SYNTHETIC FUEL
A liquid fuel obtained from coal, natural gas, or biomass.—renewable

Pros:
· Measurably better low and high temperature viscosity performance
· Better chemical and sheer stability
· Decreased evaporative loss
Cons:
· Very expensive
· High hydrogen consumption
· Lower friction than conventional oil
2 Uses:
· Alternative for car fuels
· produces heat

COGENERATION
Use of a heat engine or a power station to simultaneously generate both electricity and useful heat—renewable

Pros:
· Less fuel needs to be consumed to produce the same amount of useful energy
· Useful for heating big areas with large heating needs
· Reduces green house gases
Cons:
· Heat can only be used on site or very close to the plant
· Requires heavily insulated pipes, which are expensive and inefficient
· Tends to lose power more readily
2 Uses:
· For heating and cooling systems
· Electricity production

BIOMASS FUEL
Composed of organic material obtained mainly from plants and animals—renewable

Pros:
· Easily available resource
· Keeps us pollution free
· Produces heat and electricity during biomass energy production
Cons:
· May be produced from animal waste
· Greenhouse gases
· Process of production is very expensive
2 Uses:
· Methane from waste
· Alcohol made from sugar or starch

WIND

Conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships—renewable

Pros:
· Most useful form of energy
· Most inexpensive form of energy
· Does not produce any green house gases
Cons:
· Purchase/setup of wind turbines can be expensive
· Wind turbines can be damaged/destroyed in storms
· Machines to produce wind energy are very noisy
2 Uses:
· Sail boats
· Wind mills

NUCLEAR ENERGY
Produced from controlled nuclear reactions—non-renewable

Pros:
· Emits low amounts of carbon dioxide
· Technology is readily available
· It’s possible to generate a high amount of electrical energy in one single plant
Cons:
· Waste is extremely dangerous
· Radiation
· Energy source is uranium and uranium is a scarce resource
2 Uses:
· Produces electricity
· Powers submarines

FUSION
Process by which multiple like charged atomic nuclei join together to form a heavier nucleus—renewable

Pros:
· Not radioactive
· Can be stopped at any time (no meltdowns)
· Inexhaustible energy supply that could eliminate most of the world’s dependence on other fuels
Cons:
· Ignition temperature is extremely high
· Difficult to contain
· Very expensive
2 Uses:
· Combustible fuel production
· District heating

SOLAR
Suns rays that reach earth—renewable
Pros:
· Panels give off no pollution
· Can be very efficient in a large area of the globe
· Allows less dependency on worlds fossil fuels
Cons:
· Weather can effect its efficiency
· Only generated during the day
· Solar panels installation---very costly
2 Uses:
· Lighting
· Heat

TIDAL
Harnesses the water flow created by the moon orbiting earth; currents turn generator turbines—renewable
Pros:
· Free after dams are built
· Quite
· Non-polluting
Cons:
· Max energy is limited to 2.5 terawatts
· Equipment can be damaged by strong currents
· Widespread environmental damage to the aquatic ecosystem
2 Uses:
· Electricity
· Tidal energy generators
